Mounting

The 295SLS is designed to be mounted directly onto the dash or
other surface through the use of a bail strap mounting bracket.
The unit may also be mounted into your vehicle’s console (if so
equipped). Regardless of the style selected, be sure to

observe the air bag warning on the cover of this manual.

Bail Strap Mount

1. Position the bail strap in the selected mounting location.
Using an awl or other suitable tool, scribe the surface where
the mounting holes are to be drilled.

Caution: As mounting this unit will require drilling, it is

absolutely necessary to make sure that no other
vehicle components could be damaged in the
process. Check both sides of the mounting
surface before starting. If damage is likely,
select a different mounting location.

2. Drill the mounting holes in the areas scribed in step 1. The
size of the dri ll bit should be determi ned by the size of the
mounting hardware used and thickness of the mounting
surface.

3. Secure the bail strap to the mounting location.

Note: There are 2 sets of holes on the Bail Strap for

positioning the unit at 2 different heights.

4. Secure the siren to the bail bracket using the provided
hardware as shown below.

5. Tighten the Acorn nut firmly.

Console Mount

Console manufacturers offer mounting kits that include all the
necessary hardware and brackets required to mount this unit into
their console. The console mount brackets are secured onto the
unit the same way the bail bracket is (except for the addition of
two flat washers that must be inserted between the siren and the
bracket). Please refer to the manual included with your console
for specific information on securing the siren/mounting bracket
assembly onto the console.

NOTE: Due to the lack of air flow within a console, prolonged
operation of this siren may require the console to be
modified to improve ventilation.

Microphone Clip

A microphone clip is included with this product. The installer
must refer to the Air Bag Warning below before installing this
clip.

become a projectile that could cause serious
personal injury or death. Refer to your vehicle
owners manual to learn the air bag deployment
zones for the vehicle. The User/Inst a ller ass umes full
responsibility to determine proper mounting
location, based on providing ultimate safety to all
passengers inside the vehicle.
